Ao tentar executar o certbot para criar um certificado SSL Lets Encrypt deparei-me com o seguinte erro:

Isso acontece porque o certbot depende do Python para executar e nas últimas semanas parece estar havendo problemas com as dependências de pacotes entre os dois.
Para sanar este problema específico instale o seguinte pacote:
> apt-get install python-pip
Em seguida execute:
> pip install ndg-httpsclient
Aguarde o fim da instalação e execute o certbot novamente.
